Color and patina for steel staircase
(-----) January 24, 2008
I am installing newly fabricated steel parts in a commercial building remodel for our violin making workshop. Do you know of a product that can color or darken new shiny steel in order to make it appear darker or give it a older patina. Perhaps a bluing or gray liquid dye?

Try kitchen salt solution(rusty finish,5% must work,you can add few drops of Muriatic Acid [affil. link to info/product on Amazon] -- spray it or paint it on.If you want dark finish try 20 gm tannic acid/15ml phosphoric acid/ 1 lit water solution(dark grey-black). There are many proprietary solutions too. Hope it helps and good luck!Goran Budija
